Which of the following expression are legal in Java 17 Which

17. Which of the following expressions are legal in Java? If an expression is not legal, explain why. If it is legal, give its value. Assume x is an int variable with the value 5, y is a double variable with value 3.5, and b is a boolean variable with value false. A. (3 4 5) /3 4 5 2 6 D. 3 ++x. E. 0/0 F. y/x G. a b. H. a \"b \"c\" J. \"3\" (2 1) K. false true L. false true M. c\' 99 N. (3+4 5) & (4.6) I b (3 4) I (5 5) & (3

Solution

int x = 5;

double y = 3.5;

boolean b = false;

A.   (3+4/5)/3 = 1

B.    3*4%5/2*6 = 6

C.   3+ x++ = 8

D. 3+ ++x = 9

E. 0/0 ------Invalid

F. y/x = 0.7

G. \'a\' +\'b\' = 195(97+98(ascii values))

H. \'a\' + \'b\' +\"c\" = 195c

I. \"3\" +2+1 = 321

J. \"3\" +(2+1) = 33

K. false<true ---------Invalid

L. false = = true   ----------Invalid

M. \'c\' == 99 true

N. (3+4>5)&(4=6)|b -----------Invalid

O. !((3>4)|(5!=5))&(3<(4*0)) false

P.   !(3>4|5 != 5&3<4*0)-----------Invalid

int x = 5;

x += 4;    // x= 9

x *= 2;   // x= 18            (9*2)

x /= 3; // x= 6              (18/3)

x %= 4;   // x= 2          (6%4=2)
